' LUBRICA'IING- DEVICE FOR AUIEOll/DIIBIHES.

Application filed December 7, 1921. Serial No. 520,636.

To all whom may concern:

Belt known that I, JOE)? Gn'rwnm, a c1t1zen of the Unltcd States, residing vat Shelburn, .inthe county of Linn and State It is the principal object of the invention to associate the device witha removable transmission cover so'that when the engine is in operation, a quantity of oil will be splashed into a pocket and collected in a receiving cylinder so that when the machine is climbing a hill, oil will be supplied to the front crank shaftbearing and timing gears through a conduit leading from the rather highly elevated cylinderto-these elements. i r a 7 Another object of the invention is to generally improve upon devices of this class by providing one of extreme simplicity and durability which is practical, and is such in construction that itcan be installed by unskilled'hands.

Another and very important object of the invention is to provide an attachment of this class wherein: the aforesaid conduit is in the form ofa small piping terminating with a'short vertically disposed piece which is adapted to extend loosely through the alined existing bolt holes in the oil pan and crank case. fience, when installing the device it is entirely'unnecessary to drill any holes whatsoever in order to apply the lubricant to the desired point.

A further object of the invention is to provide an attachment embodying the aforesaid construction together with a novel connecting bar or member having a hole through which said shortpiece of pipe extends, this bar being connected with the oil,

pan by the existing bolts which serve to connect the latter with the inwardly. di-

rected flange on the bottom of the crank case.

.of this part is provided with a notch 3.

In the accompanying drawings forming a part of this specification and in which like parts throughout the same: Figure l is an elevational view'of a conventional type of automobile engine, with parts of the crank case and oil pan shown in section, showing my improved 1ubr1cating attachment associated therewith.

In tliedrawings, the letter C designates an automobile engine crank case, P designates the removable oil pan and T the removable section of the transmission housing which is formed with. an opening closed by a removable cover "plate to enable access to be had to the bands and other adjacent parts. 7 i i The invention, as before indicated, resides in the employment of a new form of cover'plate 1 which is shaped'like the one now in use and is secured in place by the existing bolts. The improved cover plate how-v ever is equipped with a rearwardly tapered pocket 2 which is open at its forward end to permit oil contained in the crank case to be splashedlinto this pocket by the flywheel which is located just in front of it.

To enable the oil to be more effectively.

thrown into the pocket, the right-hand side AS wardly and discharges through an opening 4 formed in the cover plate] and passes through this opening and through a comparatively Wide curved conduit "5 which communicates with a receiving cylinder 6. This cylinder is disposed adjacent the right hand edge of the cover plate and is positioned on a plane below the'plate. A considerable quantity of oil is collected in this numerals are employed to designate like receiving cylinder and is conveyed back to the crank case through the small pipe 7 which is connected with one end thereof and discharges into the crank case. A continuous circulation oi the oil is thus kept up even when the machine is going up a grade. Consequently, the front crank shalt bearing and timing gears are thus continuously lubricated instead of being neglected as they are new with the present system.

It has been hereinbefore indicated that particular emphasisis to be laid on the manner of connecting the short upwardly directed piece of pipe '8 with the oil pan P and although the means could be of some other construction, 1 preferably employ a bar 9 having. at its center a-hole 10 for passage of the pipe 8 and provided at its opposite ends with holes ii for passage of the bolts B. This bar is ot a length to permit the existing bolts which serve to connect the oil pan with the crank case to he used for connect ing the bar to the oil pan. In practice, an elongated gasket 12 will be arranged between the and oil pan to prevent leakage and the aforesaid hole 10 in the center of the bar will he screw-threaded to permit the short pipe 8 to be tapped therein. It may be that the bolt holes now under consideration may vary somewhat in size on different machinesand in order to overcome the necessity of employing special pieces of pipes of a size and threaded to accurately lit the holes, the specific connecting means described is preferably employed.

In installing the device, the existing transmission cover plate is removed and the improved plate substituted therefor, the oil retaining cylinder being located on the right-hand side of the machine. The forward three bolts B which assist in connecting the 'oil pan P with the crank case are removed and the connecting bar '9 bolted in place so that the centralthreaded hole 10 registers wit-h the adjacent bolt holes in the pan and crank case. i'issuming that the pipe '7 has been connected with the cylinder, the short upwardly directed piece 8 is passed through the hole 10 and bolt holes so as to project into the crank case. Hence, when the machine is in operation, the oil contained in the bottom of the crank case adjacent the fly wheel will be carried upwardly by the latter and thrown in the open end of the aforesaid pocket. From the latter, it will flow through the discharge opening e, conduit 5 and will be collected in the receiving cylinder 6. From the latter, it will pass through the pipes 7 and 8 and back to the cranl case to insure an effective circulation and proper lubrication or all parts of the engine, especially the forward bearings and timing gears when the machine is -:-linibing a hill. The piping '7 is detachably connected with the aforesaid receiving cylinder and it is therefore very easv to disconnect the pipe to enable the co r61 plate to he removed so that access can be had to the transmission bands, drums and other ments.

By carefully considering the description in connection with .he that s.v persons fa:- niiliarwith oi this class will doubtless ee able to obtain a clear understand ing of the invention. Therefore, a more lengthy and detailed. description of the iii-- vention is deemed unnecessary.

Since probably the best results may he obtained with the construction and arrange ment herein shown and described, this taken as the preferred embodiment oi the invention. However, I wish it to be understood that minor changes coming within the scope of the invention as claimed may be resorted to if desired.

I claim:

A transmission cover plate provided on underlace with an integral rearwardly open at its forwardend and having a slot formed in one verticalside and open-- ing throughthe free end of said side to facilitate collecting of voil firm a rotating fly-wheel, said plate also bein provided at the closed rear end of said pocket with a discharge opening, a substantially cylindrical receiving pocket alongside one oi the plate on a plane below the undertace oi the latter. and a transverse conduit loading from the aforesaid discharge openin to the receiving pocket, both of said pockets. plate and conduit being all one integral stmctuJe,v and the conduit bei the same in width as the length of thereceiving pocket.

In testimony whereoi l have hereunto set my hand.
